ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 294,815, dated March 11, 1884.

Application filed October 17, 1883. (X0 model.)

To all whom it may concern.-

Be it known that I, FRED J. Scrrnrr, a citizen of the United States, residing at Marshall, in the county of Saline, in the State of Missouri, have invented a new and useful Fire- Proof Chain or Cable Elevator for Flouring- Mills, of which the following is a specification.

My invention relates to an improvement in elevators, adapted more particularly for use in flooring-mills, the object of the same being to provide a fireproof device that will occupy but little space and that will combine simplicity and economy in construction with durability and efficiency in use; and with these ends in View my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in front elevation, partly in section, of an elevator embodying my invention. Fig. 2 is a detached view of one of the cups, and Figs. 3, 4, and 5 are detached views of the parts employed for securing the cups to the elevatorchains.

A represents the elevator, made wholly of metal, and consisting, essentially, of a base, B, having a false bottom, 0, two tubular spouts, E, a cap, F, a hopper, G, into which the material is discharged from the cups secured to a chain, and two sprocket-wheels.

The base B can be of any size and shape, and is provided with the false bottom 0, arranged concentric with the sprocket-wheel D. This wheel D is provided with recesses situated equidistant apart, with which the cups H register, thereby preventing the crushing of the cups or a straining of the chain. This wheel is also provided between the recesses with teeth, which latter take into the chain and move the latter without throwing any of the strain on the cups. This wheel I) is journaled to a suitable bearing, 2), which latter is vertically adjustable by means of the screwthreaded rod and the hand-wheel J. By this arrangement the chain can be tightened or loosened very readily without stopping the machine.

The wheel D, situated within the cap F, is secured to the shaft 0. This'cap F and base B are connected together by the tubular spouts- E, which latter are preferably made of sheet metal pipe jointed in any suitable manner.

These pipes are sufficiently large to allow the cups to travel freely therein, and communicate at opposite ends, respectively, with the base and cap.

- The chain, which can be of any suitable kind, together with the cups H, which are se; cured thereto at suitable intervals apart, form an endless chain, which latter passes through both spouts and around both wheels. The buckets or cups secured to the chain receive the grain below the wheel D and carry it up one of the spouts and discharge it into the hopper G, which latter is secured to the lower edge of the cap F. This hopper is provided with a metallic spout, K, adapted to deliver the grain to any desired portion of the mill.

The buckets or cups H consist, essentially, of a saucer-shaped receptacle provided with a central perforation for the passage of the eyebolt L. This bolt is providedwith a shoulder, d, on which the cup rests, and with a screwthreaded end. A sleeve, M, is then placed on the bolt, and the parts are secured together by the socketed hook N, which latter is screwed onto the screw-threaded upper end of the eyebolt. This socketed screw is adapted to be secured to one end of a small section of chain, while the opposite end of the same section is secured to the eye of the bolt next above.

An elevator of this character can be con- -structed at a small cost, and beside occupying but little space is entirely fire-proof.

It is evident that slight changes in the construction and relative arrangement of the several parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do not confine myself to the exact construction shown and described, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isv l 1. In an elevator, the combination, with two upright metallic spouts, a cap secured to the upper ends of said spouts, and a hopper provided with a dischargepipe, 01: suitable chaiir supporting wheels and chain and buckets, substantially as set forth.

2. In an elevator, the combination, with a suitable base and sprocket-wheel, a suitable cap provided with a similar wheel, and a hopper communicating with the cap and provided with a discharge-pipe, of two parallel tubular spouts connecting the base and cap, and a chain and buckets secured to the chain, the parts being arranged as described.

3. The combination, with a base, cap, hopper, and sprocket-wheels, one of the latterbeing adjustable, of the parallel tubular spouts connecting the cap and base and the chain and buckets, all of the above parts being arranged substantially as described.

4-. In an elevator, the combination, with a chain and buckets, of the sprocket-wheels, each provided with recesses situated equidistant apart, and teeth between the said recesses for engaging the chain, substantially as set forth.

'5. An elevator-buel-;et consisting, essentially, of a saucer-shaped receptacle, an eye bolt, a sleeve, and a soekcted hook, all of the above parts combined as described.
